Structuring Framework for Early Validation of Product Ideas
The advancing digitalization leads to new challenges in the development of new product ideas. The systems, which need to be developed, are becoming increasingly complex. As complexity rises, so does the slowness of organizations. In order to remain innovative and be able to react quickly to changes in the market, validation approaches offer great potential. An essential focus is the early, customer-centric and continuous validation of development artefacts. This is the only way to cope with shorter development cycles, and develop products that address a real need. To plan a validation, engineers need to have an idea about the possibilities within a validation. This paper presents a structuring framework for early validation of product ideas, which contains the three tools of Validation Map, Building Block Cards and Validation Canvas. The objective is to enable easier planning of validation experiments

Measurement of the proton form factor by studying
Using data samples collected with the BESIII detector at the BEPCII collider,
we measure the Born cross section of at 12
center-of-mass energies from 2232.4 to 3671.0 MeV. The corresponding effective
electromagnetic form factor of the proton is deduced under the assumption that
the electric and magnetic form factors are equal . In
addition, the ratio of electric to magnetic form factors, , and
are extracted by fitting the polar angle distribution of the proton
for the data samples with larger statistics, namely at 2232.4 and
2400.0 MeV and a combined sample at = 3050.0, 3060.0 and 3080.0 MeV,
respectively. The measured cross sections are in agreement with recent results
from BaBar, improving the overall uncertainty by about 30\%. The
ratios are close to unity and consistent with BaBar results in
the same region, which indicates the data are consistent with the
assumption that within uncertainties.Comment: 13 pages, 24 figure
Observation of the isospin-violating decay
Using a sample of 1.31 billion events collected with the BESIII
detector at the BEPCII collider, the decays and are
investigated. The isospin violating decay
with , is observed for the first time. The width of the
obtained from the dipion mass spectrum is found to be much smaller
than the world average value. In the mass spectrum, there
is evidence of production. By studying the decay , the branching fractions of and
, as well as their ratio, are also measured.Comment: 10 pages, 10 figures, published in Phys. Rev.
An amplitude analysis of the system produced in radiative decays
An amplitude analysis of the system produced in radiative
decays is presented. In particular, a piecewise function that
describes the dynamics of the system is determined as a
function of from an analysis of the
decays collected by the BESIII detector.
The goal of this analysis is to provide a description of the scalar and tensor
components of the system while making minimal assumptions about
the properties or number of poles in the amplitude. Such a model-independent
description allows one to integrate these results with other related results
from complementary reactions in the development of phenomenological models,
which can then be used to directly fit experimental data to obtain parameters
of interest. The branching fraction of is
determined to be , where the uncertainty is
systematic only and the statistical uncertainty is negligible.Comment: Submitted to Phys. Rev. D 19 pages, 4 figure

A neutral structure in the D (D) over bar* system around the D (D) over bar* mass threshold is observed with a statistical significance greater than 10 sigma in the processes e(+)e(-) -> D+D*(-)pi(0) + c.c. and e(+)e(-) -> D-0(D) over bar*(0)pi(0) + c.c. at root s = 4.226 and 4.257 GeV in the BESIII experiment. The structure is denoted as Z(c)(3885)(0). Assuming the presence of a resonance, its pole mass and width are determined to be [3885.7(-5.7)(+4.3) (stat) +/- 8.4(syst)] MeV/c(2) and [35(-12)(+11) (stat) +/- 15(syst)] MeV, respectively. The Born cross sections are measured to be sigma[e(+)e(-) -> Z(c)(3885)(0)pi(0); Z(c)(3885)(0) -> D (D) over bar*] = [77 +/- 13(stat) +/- 17(syst)] pb at 4.226 GeV and [47 +/- 9(stat) +/- 10(syst)] pb at 4.257 GeV. The ratio of decay rates B[Z(c)(3885)(0) -> D+D*(-) + c.c.]/B[Z(c)(3885)(0) -> D-0(D) over bar*(0) + c.c.] is determined to be 0.96 +/- 0.18(stat) +/- 0.12(syst), consistent with no isospin violation in the process, Z(c)(3885)(0) -> D (D) over bar*.Funding: The BESIII Collaboration thanks the staff of BEPCII and the IHEP computing center for their strong support.

A COLISÃO DE PRINCÍPIOS E SUA SOLUÇÃO NO EXEMPLO DO DIREITO À IMAGEM E À LIBERDADE DE IMPRENSA
Este trabalho analisa se a liberdade de imprensa e o direito à informação podem prevalecer diante do direito à intimidade e do direito à imagem na transmissão de imagens de pessoas comuns em lugares públicos. Esta análise será feita diante dos princípios da inviolabilidade da intimidade, do direito à imagem, do direito à informação, da liberdade da imprensa, da dignidade humana e da proporcionalidade. O tema é atual, porque diariamente se vê, na televisão, nos jornais e em revistas retratos de pessoas tirados sem a devida autorização. Serão utilizados o método dedutivo e as técnicas da pesquisa bibliográfica e jurisprudencial. Conclui-se que o principio da liberdade de imprensa e o direito à informação não justificam a filmagem não-autorizada de meros espectadores de eventos e que, na ocorrência de filmagens não- autorizadas de participantes, cada caso deve ser ponderado com base no princípio da proporcionalidade
Online servicescape dimensions as predictors of website trust in the South African domestic airline industry
Increased costs, competition and a dynamic environment have led to South African domestic airlines relying more on their own websites as outlets for airline tickets. Customers’ e-commerce uptake with respect to buying airline tickets online has been slow, attributed mostly to a lack of website trust. A well-designed online service scape has been identified as an important contributor to website trust by several authors, but not yet in this particular context or industry. This study investigates the extent to which three online service scape dimensions predict website trust in the South African domestic airline industry. A quantitative and descriptive research design was followed, and 300 responses were collected through self-administered questionnaires from domestic airline passengers who had purchased an airline e-ticket from a website. A multiple regression analysis indicates that online financial security is the best predictor of website trust, followed by layout and functionality and aesthetic appeal. Consequently, it is recommended that South African domestic airlines that wish to cultivate website trust should focus primarily on enhancing the online financial security of their websites, followed by customising the layout and functionality of their websites, and lastly improving aesthetic appeal by increasing the entertainment value of their websites
